1o hicle, permitting the attachment to be always convenient and ready for use.

In many instances when hoisting the rear part of an automobile, it is very difficult, and particularly when the roadway is slippery or muddy to retain a lifting jack in position under the rear springs. It is even tedious to insert the lifting jack in place.

It is therefore another purpose to avoid this difficulty by providing an attachment on both of.

I the rear springs, whereby when desired to change a tire, the head of the lifting bar of a lifting jack may be guided into position under the spring, and after placing the jack in its proper position the handle of the jack can be easily actuated for moving the lifting bar step by step and hence hoist the automobile.

It is to be understood that the particulars.

herein given are in no way limitative, and that while still keeping within the scope of the invenso tion, any desired modification of details and proport-ions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth,

55 shown in the drawing and claimed.

In the drawing:-

Figure 1 is a view in side elevation of a portion of the rear frame of a motor vehicle, showing the usual spring, and illustrating the lifting jack ar- 4oranged in place.

Figure 2 is a perspective view of the attachment removed, showing the channel way and the means for attaching.

Figure 3 is a sectional view on line 33 of Figure 2.

Figure 4 is a sectional view on line 44 of Figure 1.

Figure 5 is a sectional view on line 5--5 of Figure 1.

Figure 6 is a view in side elevation of a portion of one of the rear springs, showing one of the leaves of the spring provided with depending longitudinal flanges.

Referring to the drawing 1 identifies the improved attachment which comprises a body which may be any suitable length for the purpose intended, and may be any suitable shape and width. This body has opposite longitudinal flanges 3, which merge into lateral flanges 4, and

in this case the body is in the form of a channel, the channel 5 adapted to receive the head of the lifting bar of an automobile lifting jack. One end of this body constituting the attachment has an extension 6, which fits between the saddle 7 (through which the two legs 8 of the U bolts 9 pass) and the lower leaf of the rear spring 10 of a motor vehicle frame 11, and after tightening up the nuts on the legs 8 of the U bolts 9 the 7 extension 6 of the body constituting the attachment is secured in place.

The other end of the body (the channel of which at said other end is open) is provided with lateral ears or lugs 12, which are apertured for the reception of the lugs 13 of a U bolt 14 (which straddles the spring) so thatv by means of fasten- 7 ing nuts 15 the other end of the body is securely fastened to the spring. This attachment of the body to the spring is permanent, and whenever it is necessary to hoist the rear'of an automobile, though it is possible that the attachment can be, 30 if desired, applied to the forward springs, the head of the lifting bar of a lifting jack may be easily inserted and guided into the channel of the body and arranged in position as illustrated in Figure 1, whether the automobile may be on a slippery muddy or uneven road. When arranging the lifting jack in position the head of the lifting bar is limited in such position by means of an abutment wall 16, which may be formed in the channel in any suitable way, preferably struck down from the extension 6. V

After inserting the lifting jack 1'7 in position as illustrated in Figure 1 the operating lever of a lifting jack can be actuated for imparting movement to the lifting bar of a jack and thereby hoist the motor vehicle.

Referring to Figure 6 one of the rear springs identified as 19 has its lower leaf formed with longitudinal flanges 20 (which have laterally extending portions) thereby causing a channel 21 1 to be formed to receive the head of the lifting barof a lifting jack. In this instance the head of the lifting bar is guided into the channel. It is also obvious that the spring when constructed can be manufactured as disclosed in Figure 6.

The invention having been set forth, what is claimed is:

As an article of manufacture, a lifting jack attachment for motor vehicles, comprising an elongated body having depending side flanges with 110 extension and bent downwardly at one end of the channel to limit the position of the head of the lifting bar of the lifting jackwhen inserted in the channel, the other end of the body adjacent said entrance mouth having lateral ears, and means comprising a U shaped saddle straddling the spring with its legs passing through the ears with means on the ends of the legs against the under surfaces of the ears for tightening the body against the spring in conformity with its curvature.
